Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467140, here are decompositions:

7 + 31467133 = 31467140
13 + 31467127 = 31467140
37 + 31467103 = 31467140
73 + 31467067 = 31467140
151 + 31466989 = 31467140
163 + 31466977 = 31467140
241 + 31466899 = 31467140
283 + 31466857 = 31467140

Showing the first eight; more decompositions exist.
